T all whom it may concern Be it known that'I, JOHN 0. MORRIS, a citizen of the United States, residing-at avenport, in the county of Scott, State of lowa, have inventedl certain -new and useful lmprovements in Ash-Screens; and I do hereby declare the following to be a full, clear, and-exact description of the invention,

' such as will enable others skilled in the art to which it appertains to same. n

This invention relates to ash screens. The object of the invention resides in the provision of an ash screen Vwhich can be readily inserted through the ash door of Va furnace in position to directly receive the ashes as the grate is shaken, or dumped said screen embodying a' structure permitting easy reciprocation thereof while disposed in the furnace to effect screening of make and use the kthe ashes. l

Afurther object of the invention resides in the provision of an ash screen whichwhen inserted in the furnace and operated to screen the ashes will prevent dust from escapingfromthe interior of the furnace to the exterior thereof.

A still further kobject of the invention resides in the provision of an ash .screen which can be removed from the interior of a furnace without disturbing that portion of the ashes which have passed throughthe screen to a position upon the bottom of the fur-V nace.

Another object of the invention resides in the provision of an ash screen of the character referred to which will be simple in construction, eflicient in use and which may be manufactured at a comparatively small cost.

With the above and other objects in view Ythe invention consists in the details of cond struction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim. x

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which` Figure 1 is a vertical section of a portion of a furnace showing theimproved screen in position to receive ashes upon shaking or umping the grate; Fig. 2, a plan view of the screen ;V Fig. 3, a section on the line 3-3 of Fig. 2; and 1`4 of Fig.- 2. l Referring to the drawings the improved screen is shown as comprising a frame A which embodies front and rear members l0 and 11 and side members 13 and 14 which latter constitute the supporting runners of the screen. The runners 13 and 11 are connected at their forward ends by the member 10 and at their rear ends by the member 11. A cleat 15 is secured against the member 11 of the frame A as clearly shown in the drawing. To this frame A and cleat 15 is secured a screen 16 in any suitable manner. On the upper edges of the members 10, 13 and 14 are secured members 17, 18, and 19 respectively which form with the upper part of the member 11a tray to receive the ashes and other materials shaken or dumped from the grates and also further securing the screen 16 by clamping same between the members 17, 18 and 19 and the frame A.

The upper edge of the side members 18 and 19 are beveled as at 20 for a purpose that will now appear. Hingedly secured to 4, a section on the line the side members 18 and 19 are wings or leaves 21 and`22 respectively, which when actively disposed are adapted to rest upon the upper beveled edge 20 of respective members 18 and 19, whereby said wings are supported in an. Voutward inclination. These wings 21 and 22 are designed to be utilized only when the width of the grate of the furnace isin excess of the width of the ash pit door and the screen 16, the wings under such condition serving to catch ashes descending beyond the limits of the screen and directing same upon the latter.

he rear member 11 of frame A is provided with a handle 23 for convenience in inserting the screen through the ash-pit oor of a Vfurnace and also for convenience in effecting reciprocation of the device in the operation Vof treating the ashes.

It will be noted that during the screening operation that the passage of the dust to the exterior of the furnace is prevented by the passing of air into the fire-box due to the draft of the furnace and chimney. It will be further noted that as the member 10 is relatively narrow, the whole screen may be withdrawn from the interior of the furnace without disturbing the material which has passed through the screen.

at is claimed is A device of the class described comprising 2 Y l 1,150,615V Y a frame including supporting runners havclined positionzto receive the material fall- 10 ing their ends connected by cross bars, on ingV outside of the limits of the screen.

the upper edge of which is secured a screen, In testimony-whereof, I affix my signaa tray secured to upper edge of the supportture, in the presence of two Witnesses.
